Summary
🤩
Rockstar🎓
Top SchoolConglong Li is a Senior Research Scientist at Google DeepMind Japan with a decade of experience blending systems engineering and AI research, focusing on improving thinking, multilingual, and multimodal capabilities in Gemini models. He holds a CMU PhD and previously advanced large-scale training and efficiency features on Microsoft’s DeepSpeed—contributing kernel fixes, 1-bit Adam/LAMB optimizers, and curriculum learning for transformer training. His work habitually combines rigorous performance analysis with algorithm and policy design to eliminate inefficiencies across deep learning, similarity search, distributed caching, networks, and architecture. Notably, he has translated research into production impact before—e.g., learned early-termination for ANN search and caching strategies that demonstrated substantial cost savings. Based in Tokyo, he brings both deep academic rigor and practical open-source contributions to scaling state-of-the-art models.
